  2. Microsoft CryptoAPI - Wikipedia

    en.wikipedia.org/wiki/Microsoft_CryptoAPI

    The Microsoft Windows platform specific Cryptographic Application Programming Interface (also known variously as CryptoAPI, Microsoft Cryptography API, MS-CAPI or simply CAPI) is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Windows-based applications using cryptography.

  3. Cryptographic Service Provider - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_Service_Provider

    The CAPI/CSP architecture had its origins in the era of restrictive US government controls on the export of cryptography. Microsoft's default or "base" CSP then included with Windows was limited to 512-bit RSA public-key cryptography and 40-bit symmetric cryptography, the maximum key lengths permitted in exportable mass market software at the time.

  4. HTTP Public Key Pinning - Wikipedia

    en.wikipedia.org/wiki/HTTP_Public_Key_Pinning

    For example, attackers might compromise a certificate authority, and then mis-issue certificates for a web origin. To combat this risk, the HTTPS web server serves a list of “pinned” public key hashes valid for a given time; on subsequent connections, during that validity time, clients expect the server to use one or more of those public ...

  5. Comparison of cryptography libraries - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_cryptography...

    This table denotes, if a cryptography library provides the technical requisites for FIPS 140, and the status of their FIPS 140 certification (according to NIST's CMVP search, [27] modules in process list [28] and implementation under test list).

  6. Comparison of cryptographic hash functions - Wikipedia

    Algorithm Output size (bits) Internal state size [note 1] Block size Length size Word size Rounds; BLAKE2b: 512 512 1024 128 [note 2]: 64 12 BLAKE2s: 256 256 512 64 [note 3]: 32 10

  7. Critical security parameter - Wikipedia

    en.wikipedia.org/wiki/Critical_Security_Parameter

    In cryptography, a critical security parameter (CSP) [1] is information that is either user or system defined and is used to operate a cryptography module in processing encryption functions including cryptographic keys and authentication data, such as passwords, the disclosure or modification of which can compromise the security of a cryptographic module or the security of the information ...

  8. Mask generation function - Wikipedia

    en.wikipedia.org/wiki/Mask_generation_function

    Convert counter to an octet string C of length 4 with the primitive I2OSP: C = I2OSP (counter, 4) C = int. to_bytes (counter, 4, "big") # b. Concatenate the hash of the seed Z and C to the octet string T: T = T || Hash (Z || C) T += hash_func (seed + C). digest counter += 1 # 4. Output the leading l octets of T as the octet string mask. return ...

  9. Cryptographically secure pseudorandom number generator

    en.wikipedia.org/wiki/Cryptographically_secure...

    In the asymptotic setting, a family of deterministic polynomial time computable functions : {,} {,} for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it stretches the length of its input (() > for any k), and if its output is computationally indistinguishable from true randomness, i.e. for any probabilistic polynomial time algorithm A, which ...
